anbhc, good for you.
I have been trying to get 2 BE award in June to PVG from Boston, was quoted 240K, finally got 2 Y for 120K 2 weeks ago thru the "calendar". Checked last week and the "calendar" showed low award level available, but won't pull up the seats.
Called Delta, the poor guy said he was just yelled at by the last caller who had similar problem in pulling up award tickets when "calendar" showed availability. He tried to pull up what I found in "calendar" and had similar problem. After he put me on hold he was able to finally get me 2 BE award from BOS-DTW-PVG for 180K each, 60K outbound 120K return. Not the best, but I will take whatever I can to burn my miles while I can.
